Flask closure with hinged lid and tamper indicating element

ABSTRACT

A closure for a flask (G) with a spout ( 19 ) and a hinged lid ( 2 ) has a tamper indicating element ( 7,8 ). The tamper indicating element ( 7,8 ) consists of a part ( 7 ), which is fixed to the flask (G) and a tearable strip ( 8 ). Only when the strip ( 8 ) is removed, the hinged lid ( 2 ) can be lifted from the spout  19 ).

This specification refers to a CONSTRUCTING ARRANGEMENT INTRODUCED IN ALID, which will be used in flasks in general, and more specifically inflasks containing edible oil, and which is provided with means fordetecting tampering of its opening, thus assuring total integrity of itscontents.

BACKGROUND OF THE ART

Various types of lids incorporating means capable of identifying itstampering are already known in the prior art, and this is usuallyobtained by the use of low resistance lines or small frangible rods,which will break when opening the lid; however, all of them present asthe main inconvenience the fact that the breaking elements can be, insome cases regenerated, most of the times even in a quite simple way,thus allowing fraud practice against the user.

On the other hand, the currently known lids in the prior art whichincorporate more effective means through seals formed from removablestrips; however such lids present as a disadvantage the fact that, afterremoving the seal, when opening the lid, it is found there are no meansleft which can help the retention of the lower outer portion of the lidagainst the outer edge of the neck, since that, in most of the times,this removable strip which constitutes the seal is applied exactly onthe lower part of the lid.

FUNDAMENTS OF THE MODEL

With the aim of overcoming all the inconvenience due to the currenttechniques a CONSTRUCTING ARRANGEMENT INTRODUCED IN A LID has beenidealized, which comprises of a cylindrical body, provided with aarticulated over-lid, said body being inserted under pressure, in theinner part of the flask neck, where it will be retained by the action ofa annular spigot, provided in the lower part of said body, whichprovides an area of interference with the surface of the inner edge ofsaid neck, being also aided by the action of the element whichconstitutes the bottom of said lid, which is presented in the form of aplane disk, on the surface of which trapezoidal slits will be made,which will be arranged in a circumferential way, having sides slightlyinclined with each other, said lid is provided, immediately above thespigot, with a circumferential flap, which acts as a stop for the higheredge of the neck, being also provided a skit, which will coverexternally the superior portion of the neck, having aggregated to it, ina removable way, the breakable strip which comprises the seal of thelid, said skirt will remain, even after the removal of the seal, helpingto retain the lid over the neck, due to its inner interference points,which will interact with the higher and lower surfaces of thecircumferential flap of said lid and with an outer radial protuberanceof the neck, the closure of said lid will be carried out through anover-lid, by means of a plane hinge, articulated with the aid of theappendix which is formed on the back portion of the innercircumferential ring of the lower surface of said over-lid, which,besides guiding the insertion of the circumferential ring into theinterior in the higher edge of the lid, to promote the waterproofing ofthe assembly, will also promote the flexibility of said plane hinge,which will happen in two stages, on the first stage the hinge will bedisplaced in relation to the its joining line the over-lid, theretention of the over-lid, when of its closure, is reached by the actionof the ferrule provided on the higher edge of said lid, which willinteract with the circumferential bead provided on the lower surface ofthe over-lid, which will be arranged between the inner circumferentialring of its lower surface and its outer circumferential flap, which,when of the closure of the assembly, will circumscribe a circumferentialbead provided on the higher surface of the circumferential flap of saidlid, being that for the opening of said lid, it is provided a pluralityof triangular shoulders, provided in line, at the higher portion of afrontal peripheral segment of the over-lid, which is orthogonallyprojected, in relation with the periphery thereof.

The CONSTRUCTING ARRANGEMENT INTRODUCED IN A LID, currently proposed,can still provide, in a constructing variant, the adoption of theelement which constitutes the bottom of said lid in the form of aconical disk, on the surface of which there will be made inclined slits,arranged in a circumferential way.

PREFERRED CONSTRUCTIVENESS OF THE MODEL

According to what has been shown on the attached figures, theCONSTRUCTING ARRANGEMENT INTRODUCED IN A LID, currently proposed,comprises a cylindrical body (1), provided with an articulated over-lid(2), said body being inserted, under pressure, on the lower part of theneck (G) of the flask, and will be retained by the action of an annularspigot (3), provided on the lower part of said body, which provides anarea of interference with the surface of the inner edge of said neck,being also helped by the action of the element which constitutes thebottom of said lid, which is presented in the form of a plane disk (4),on the surface of which trapezoidal slits (5) are made, which arearranged in a circumferential way, having the sides slightly inclinedwith each other, said lid is provided, immediately above the spigot,with a circumferential flap (6), which acts as a stop for the higheredge of the neck, being also provided a skirt (7), which will coverexternally the higher portion of the neck, having aggregated to it, in aremovable way, the breakable strip (8) which constitutes the seal of thelid, and the removal of which is effected by means of a lug element (9),which when pulled, promotes first the rupture of the points (10) and(11), and after that, its rupture in relation to said skirt, which willhappen along the low resistance line (12), which joins the seal to theskirt, such said skirt will remain, even after the removal of said seal,in order to retain said lid over the neck, and is aided by its innerpoints of interference (13), (14) and (15), which will interact with thehigher and lower surfaces, of said circumferential flap of the lid, andwith the outer hinge (16), which is articulated with the help of anappendix (17), formed on the back part of the inner circumferential ring(18) of the lower surface of the over-lid, which, besides helping toinsert said circumferential ring into the interior in the higher edge(19) of the lid, in order to obtain waterproofing of the set, alsopromotes the flexibility of said plane hinge, which will happen in twostages, on the first stage the hinge will be displaced in relation tothe its joining line (20) with the circumferential flap of said lid, andon the second stage it will be displaced in relation to its joining line(21) with the lower surface of the over-lid, the retention of theover-lid, when of its closure, is reached by the action of the ferrule(22) provided in the higher edge of said lid, which will interact withthe circumferential bead (23) provided on the lower surface of theover-lid, which is arranged between the inner circumferential ring ofits lower surface and its outer circumferential flap (24), which, whenof the closure, will bear on the circumferential bead (25), provided onthe higher surface of the circumferential flap of the lid, being thatfor the opening of lid, it is provided a plurality of triangularshoulders (26), provided in line, at the higher portion of a frontalperipheral segment of the over-lid, which is orthogonally projected, inrelation to the periphery thereof.

The CONSTRUCTING ARRANGEMENT INTRODUCED IN A LID, currently proposed,can also provide, in a constructing variant, the adoption of the elementwhich constitutes the bottom of said lid in the form of a conical disk(27), on the surface of which there are made inclined slits (28),arranged in a circumferential way.
